What Is a Radial Fan?

Fans that generate a pressure difference are called radial fans. The resulting air effect acts in the direction of centrifugal force. A centrifugal fan is a mechanical device used to move air or other gases. Like a pump, these fans have a rotating impeller and a spiral-shaped housing in which the impeller sits. Air or gas enters axially through the center, is pressurized and discharged tangentially from the impeller periphery into ducts, and is expelled through the outlet. Due to the high pressure they generate, centrifugal fans are ideal for high-pressure applications such as drying and air conditioning systems. Since all moving parts are enclosed, they also have particle-reducing properties that make them ideal for use in air pollution control and filtration systems.

Things to Consider When Selecting a Fan;

4 parameters should be considered when selecting a fan:

Required Air Flow Rate
Pressure Losses
Acceptable Noise Level
Electrical Power Connection Type

The air change rate required for the space to be ventilated depends on the intended use of the space, the number of people and items inside, and their activity levels. The table alongside shows the recommended air change coefficients for different types of spaces.

Environment	Air Change Rate
Auditoriums	6-8
Paint Ovens	25-50
Vault Rooms	3-6
Cinemas and Theaters	5-8
Commercial Kitchens	15-30
Foundries	8-15
Gymnasiums	4-6
Laundries	10-20
Indoor Swimming Pools	3-4
Restaurants	8-12
Conference Rooms	6-8
Waiting Rooms	10-15
Copy Rooms	10-15
Machine Rooms	10-40
Shops	4-8
Dry Cleaning	5-15
General Manufacturing Areas	4-8
Hospitals	8-12
Laboratories	8-15
Normal Activity (non-smoking)	29 m³/h
Normal Activity (smoking)	58 m³/h
Light Activity	45 m³/h
Heavy Activity (industrial work areas)	60 m³/h

The amount of air per person in living and working spaces, depending on activity, can help determine the required air flow rate.

Based on the information provided above, the required air flow rate is determined as follows.

Q [ m³/h ] = Air change rate coefficient (1 hour) × Space volume (m³)
Q [ m³/h ] = Number of people × Air flow rate required per person

After calculating the required air flow rate, an appropriate duct design (considering noise and air velocity criteria) must be carried out and pressure losses must be calculated. Depending on the environment in which the fan will operate, the fan type (axial, centrifugal, roof-mounted, smoke exhaust, etc.) should be selected, and the appropriate fan should be chosen from the relevant performance curve based on the determined flow rate–static pressure pair. To briefly illustrate the above with an example: an office has 5 employees, a ceiling height of 2.6 m, and a floor area of 50 m², giving a volume of 2.6 × 50 = 130 m³. The air change rate given for offices in the air change coefficient table was 4–8. Taking an average of 5: 130 × 5 = 650 m³/h air requirement. Assuming normal activity in the office: 5 persons × 29 m³ = 145 m³ for the occupants, giving a total of 650 + 145 = 795 m³/h air requirement.

Fan selection is also made based on this flow rate requirement.

After completing the airflow calculations, the installation location for the fan must be determined. Where will the fan be mounted — ceiling, wall, chimney, or ventilation duct? Another consideration is the voltage of the electrical supply to the fan. Continuing with our office example: fans are generally mounted on a wall or window in offices. If household electricity is to be used, a single-phase fan should be selected. If used in an industrial setting, a fan operating on three-phase (380 V) electricity should be used.
